V4L/DVB (4938): Cx88: Convert lgdt3302 tuning function to use dvb_pll_attach

There was a still a pre-dvb-pll set_params function for the lgdt3302 in
the cx88-dvb driver.  This patch removes that function and uses
dvb_pll_attach() for the cards that were using it (Dvico FusionHDTV 3
GOLD {Q,T}).  This way the set_params function from dvb-pll is used.
dvb_attach() is in turn used on dvb_pll_attach(), eliminating some static
dependencies on dvb-pll.  There are still a couple static dependencies on
dvb-pll remaining.
